Using UML class diagrams, create a design for the following (you can defer declaring the types for any instance variables and instance methods as long as you represent the concepts appropriately). NB: You may hand-draw your diagram or use a drawing program (your choice). Upload your finished answer for (a) and (b) as one file. (a) An Employer has one or more Employees. An Employee has exactly one Employer. Employees have attributes for their name, salary and job title (b) We are producing a vehicle registration system for the local DMV/RMV. Model the following using a UML class diagram. Read the entire specification before proceeding (this is ONE question, broken into 4 segments for readability): (i) Our interface (protocol/contract) IVehicle states that all vehicles can register() and calculateExciseTax(). These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…

Help, I making a elevator simulator. I have to use polymorphism and object oriented programming to write this code. Can someone please help me improve this code I have. The remaining code is in the pictures. Any help is appreciated. Thank You! The simulation should have 4 types of Passengers: Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements. VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators. Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators. Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. The simulation should also have 4 types…

Instructions: Create a UML diagram for a Dog class. You can get some useful information from your book Review Chapter 5 Pg. 179-180. CLASS NAME List the instance variables in the constructor. Unified Modeling Language (UML) List the methods in the class. o - indicates private o name is the variable name o string is the data type of name CLASS NAME List the instance variables in the constructor. o + indicates public o getName is the method name o o string is the return data type List the methods in the class. The second row of the UML diagram lists the instance variables in the constructor. For example -name: string Java.util. The third row of the diagram lists the methods in the class. For example, +getName(): string empty parenthesie indicate nothing is sent to the method.
Class Employee Employee -Name (string) -ID(integer) -Address(string) -Salary(double) -Nationality(string) -ExtraWHours(int) +>( Name,ID) +void setdata( Address,Salary, ExtraWHours) 1. Regarding to the UML diagram create class Customer 2. Create the constructer Employee that read the Employee Name and ID and set the Nationality to Kuwaiti 3. Use the method setdata that set the remaining class data , this method verify that the number of extra working hours is greater than 5 to set the number to ExtraWHour otherwise set the number 1 + Overtime() to this data member + . get methods 4. create gets methods for all data member 5. calculate Employee overtime in Overtime method this method return double value after calculating the overtime by using the following formula Overtime = (Salary * 0.25)* ExtraWHours Test File 1. declare the object Employee1 with Name Fahad and id 7788 2. Ask the user to enter object data (Address, Salary, ExtraWHours) for the Employee1l objects 3. Set the data for…
